constexpr back_insert_iterator<Container>& operator=( typename Container::value_type&& value ); |  | (since C++20)

Inserts the given value value to the container.

1) Results in container->push_back(value).
2) Results in container->push_back(std::move(value)).

### Parameters

value | - | the value to insert

### Return value

*this

### Example

Run this code

    #include <deque>
    #include <iostream>
    #include <iterator>

    int main()
    {
        std::deque<int> q;
        std::back_insert_iterator<std::deque<int>> it(q);

        for (int i = 0; i < 10; ++i)
            it = i; // calls q.push_back(i)

        for (auto& elem : q)
            std::cout << elem << ' ';
        std::cout << '\n';
    }

Output:
